VULCAN'IZER.

Specification of Letters Patent.

Patented .Tune 30, 1908.

Application filed January 1GY 1906. Serial No. 296,265.

5 rovernents in Vulennirers, whereof the i'olowing is a specification. reference being: had E Y to the accompanying drawings.-

lt 1s tlie object ol' my invention te provide a machine arranged to vuicunize rubber hose 1b by utilizing asupplyof stemnwithin thelmse. My invention comprises n drum having n channel upon its periphery. :nid a easing removably 'litted to sind drum und having a. channel .compleinentnry to the. channel in 15 said drum. As hereinul'tcr described. such a drum is convementlv pronded with axially alihed trunnions projecting ut its opposite ends, upon which it may be :'otnted To fucilitate the winding :ind unwinding y of the hose with respect to said channel which extends spirally upon the periphery of the drum; said hose being connected with a steam Supply pipe, exterior to said drum.

. l v invention also includes the provision i of a. steam ell-.unber within the drum, and e steen: chamber within the casing, havingr suitable steam supply connections und arranged to supplement the heating; effect of the steam within the hose and nia-intein the propertemperature during the vnlconizing operation.

The ordinary vulcnnizers heretofore eniloyed being o't' such construction as to be mited to the treatment of short lengths of hose (for instance, 5() feet) which must be jointed to form a greater length, the present Invention is advantageous in that it permits of the manufacture of any desired length (or instance 500 feet) of vulcanized hose,

404 without joints.

My invention comprises the various novel features of construction and arrangement hereinafter more deiinitely specified.

In the accompanyinnr drawings, Figure I,

is a plan view of a vulcanizer conveniently embodying my improvements. Fig. II. is a sectional View taken on the line 11,11, in Figs. I, and Hl. Fig. lll, is n sec'tional view taken on the line lll, lll, in Figs. l

and II. Fig. lV, isa plan view of a modified form of vulcanizer embodying my imrovenients, the u )per section of the casing being removed. liig. V. is a sectional view of said vulcanizcr, teken on the line V, Y, in

Figs. IV and `VI. Fig-YL is a sectional iriew of said vulcanizer. taken on the line t Vl, Y1, in Figs. lV-and V.

shown in Figsj, Il; and HI; the lower cas` ing section or hase 1 is provided with the tlnnges Q. at opposite sides of the semi-cylin dricul concavit-y 3, slotted to receive the l lts 1. whiclnextend through the flanges 7, on opposite'siiles of the eoncavity 8, in then per easing section or top 10, which latter is oroi vided` with the eye )olt 11, by which it may be removed when desired. The drum'1', is g fitted to the semi-cylindrical recesses 3, and i X, in said casing und has the s )irai channel i 1:3, upon its periphery. conipllementary to the spiral channels lo, in the casing. huid channels nre provided at opposite ends of the drinn with sockets 1T, and 18, through which with a steam supply conveniently'directed therethrough by the. conduits 2J, and 21. The peripheryr of said drum 14, is connected by the webs 24, und 25, with the hub 26, having trunnions 28, and 29, rejecting at o posite ends thereof in axiall) aline-nient. s shown in Fig. Il, said drum 14, is provided with oppositely extending lugs 32, which carry (lowel pins 33, secured by the nuts 34, in screw threaded engagement with their in ner ends, and fitted to the sockets 36, in the casing buse 1. Said sockets are conveniently ).irovided with bushings 37, which may he renewed when worn.

As indicated in Fig. I, the casing top section 10, is convenient-ly provided with lugs 38, in which are fitted dowel pins 39,-which are also fitted in the iianges 2, on the lower casing section 1, so as to insure the proper registration of said casing sections.

The vulcanizer above described may be operated as follows: The drum 14, being removed from the casing may be conveniently rotated upon its trunnions 2S, and 29, while a sufficient length of hose 19. is wound thereon in the spiral channel 15.v Said drum 14, is then lowered into the recess 3, in the easing base section 1, as indicated in Fivs. II, and lll; the alinement of the channells 15,

-ceptacle for the hose 19, beingl assured by the registration of the dowel pins 33, in the socket bushings 37. Thereupon, the casing top section 10, is lowered, conveniently bv its eye bolt 11, into the position shown in Figs. II, and III, the proper registration of the chan.-

Referring to the form of my invent-ionl the ends of the hose 1Q, extend for connection and 16, to form a continuous cylindrical re- Q Y i 892,209

nels 16, in said section 10, with the channels 15, in the drum, being assured by the registration of the dowei pins 39, in their sockets.

- The bolts 4, are then inserted in the notches in the iianges 2, and 7 and the two sections of the casing clamped together as indicated in Fig. III. Thereupon, the conduits 20, and 2l, are fitted to the projecting ends of the hose 19, and a supply of steam is directed through said conduits and through the hose 19, for such a length of time and at such a temperature as to vulcanize the latter. In order to remove the hose 19, it is of course necessary to reverse the assembling operation above described, and, the drum 14, being mounted upon its trunnions 2S, and 29, may be conveniently rotated to unwind the hose 19.

In the form of my invention shown in Figs. IV, V, and VI; the lower easing section or base 41, com rises the internal steam chamu ber 42, provi ed with the inlet 43, and outlet 44. Said base 41, has the franges 45, at opposite sides of the. semi-cylindrical concavity 46, provided with the dowel pins 47, secured by the nuts 48, and fitted to the sockets 49,

in the flanges 50, on opposite sides of the concavity 51, in the upper casing section or top 53. Said casing section 53, comprises the internal steam chamber 54, having the inlet 55, and outlet 56, and is provided with the eye-bolts 57, by which it may .be removed when desired. T he'druni 60, is fitted to the semi-cylindrical concavities 46, and 51, in

said casing and has the spiral channel 63, upon its periphery, complementary to the spiral channels 64, in the casing. Said channels are .provided at opposite ends of' said duim 60, With sockets 66, and 67, through 69, and 70. The

which the ends of the hose 68, extend for connection with a steam supply conveniently directed therethrough by the conduits periphery of said drum 60, is connected With the hubs 74, by the imperforate webs 75, on opposite ends of the drum, inclosing the steam chamber 76, having the steam inlet 78, outlet 79, and drip pipe 80. Said drum 60, is conveniently provided with trunnions 85, and 86, projectin,A at opposite ends thereof in axial alinemeiit. Said drum 60, is provided with opnositely extending lugs 88, (shown in Figs. 1V,- and V,) comprising sockets 89, in which are fitted the. dowel pins 91, which are secured by the nuts 92, in screw threaded engagement with the casing base section 41. It is to be understood that the hose 68, may be )wound upon and removed from the drum 60,

111 the same mannenas described with respect to the drum 14.

It may he noted that the construction last described, with reference to Figs. IV, V, and VI, is similar to that described with reference to Figs. I, II, and III, except that the former comprises chambers 42, 54, and 76, which may be charged with steam to supplement prising a spiral j;

hose 68, which is to be vulcanized, in the' complementary channels 63, and 64, Whereas, in the form first described, heat for the vulcanizing operation is derived solely from the steam directed throgh the hose 19, which is to he vulcanized.

It is to be understood that I do not desire to limit myself to the precise details of construction and arrangement he'ren set forth, as various modifications may be' made therein without departing from the essential features of my invention.
